Ais a transformation that changes size but no the shape , of a figure. a dilation can or a figure.\
and the 2. question in the picture

dilation, enlarge, reduce

Step-by-step explanation:

We only see one question in the picture you uploaded... the one from slide 1, with the fill-in the blanks question.

A  _DILATION_ is a transformation that changes size but no the shape , of a figure. A dilation can _ENLARGE_ or _REDUCE_ a figure.

If the dilation is done with the proper dilation points, it will change the size of the figure without altering its aspect, or deforming it.

If the scale factor is > 1, the figure will be enlarged.  If the scale factor is < 1 then the figure will be reduced.

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
